Episode 29 — Operate SIEM Platforms and Manage Log Pipelines
Security Information and Event Management (SIEM) systems convert data into situational awareness, and exam questions often test whether you can choose the right collection, correlation, and response approach. We define log sources—firewalls, IDS/IPS, endpoints, servers, and cloud services—and discuss parsing, normalization, and time synchronization. You’ll learn how correlation rules link events into alerts, how dashboards and reports deliver value to different audiences, and how data retention policies support investigations and compliance. The key is recognizing that a SIEM’s effectiveness depends on accurate, relevant, and well-tuned input rather than raw volume.
We translate those principles into daily operation examples. You’ll examine tuning thresholds to minimize alert fatigue, validating new data feeds, and verifying that timestamps, hostnames, and users resolve consistently across sources. We discuss establishing use cases, maintaining parsers, and mapping alerts to playbooks for faster triage. Troubleshooting guidance covers misconfigured collectors, storage overruns, and gaps caused by agent failures or network segmentation. You’ll also learn how to evidence SIEM health through heartbeat dashboards, sample queries, and validation reports that auditors can review. With these insights, you’ll be ready to identify on the exam which improvement or corrective action best increases detection fidelity and analytic value.
